and aortic stenosis, the parent will be able to be informed and prepared for any ailments of the heart a child may develop. A heart murmur is when the valves of the heart do not close all the way; allowing some blood to flow through the valves when the valves should stop the flow. Doctors are able to hear a swooshing sound with the aid of a stethoscope. (Valvular Heart Disease website) indicates, "the S1 is usually normal or soft. The S2 may be single because the aortic and pulmonic valve components
6.1 Hazard and Risk Assessment A hazard is a potential damage, adverse health or harm that may effects something or someone at any conditions. Other than that, the risk may be high or low, that somebody could be harmed depending on the hazards. Risk assessment is a practice that helps to improve higher quality of the develop process and manufacturing process. It is also a step to examine the failure modes of the product in order to achieve higher standard of safety and product reliability. Unfortunately
Human Development (NICHD) has conducted research where they discovered a new abnormality of the aorta that affects about 50% of females with Turner Syndrome.

Nozzle has a needle in it that works kind of like a piston that once the pressure build up the needle forces forward and sprays fuel. There is a spacer above the nozzle with the nozzle springs that force the needle down. Above the spacer is a check valve, the check valve allows the right amount of fuel into the nozzle
Introduction: Acute Rheumatic Fever (ARF) and its successive partner, Rheumatic Heart Disease (RHD), pose a serious issue in paediatric health world wide. Alarmingly New Zealand is one of the biggest contributors and has the highest recorded number of ARF cases internationally (Jaine, Baker, & Venugopal, 2008). This essay will discuss the pathophysiology and epidemiology of ARF and RHD. It will focus on the impact this illness has on Maori and Pacific Island children in particular as ARF is almost
Background Prosthetic heart valve replacement is performed in several hundred thousand patients per year worldwide and is recommended for many patients with severe valvular heart disease. Bioprosthetic heart valves and mechanical heart valves are the two major valve types. Mechanical valves are more durable than bioprosthetic valves but require lifelong anticoagulant therapy with vitamin K antagonists (warfarin) due to persistent risk of thrombosis and stroke. Warfarin has a narrow therapeutic window
Every year, thousands people get heart valve replacements for various health reasons. There are multiple options for replacement valves that can generally be put into two categories, mechanical and biological. One of the mechanical options from the 1970s and 1980s was the Bjork-Shiley valve, which became infamous because of the controversy surrounding its stress fracture failures. These failures resulted the death of about 400 people, causing the value to be taken off the market. Using various ethical
Silent Killer Today was like supposed to be just like every other day. On another early Monday morning, just like every time I had to get up 2 hours before school, I woke up and went downstairs for breakfast at 6:30. I clean the mess from last night’s dinner with my brother and get ready to go with my carpool to school, because just like every other day, gas is expensive. Funny thing about the carpool, which comes at 7:00 sharp, 7:30 came and she didn’t show up, Therefore, we ended up waking up
connective tissues throughout the body such as malformations and disfigurements of the ligaments, spinal dura, lens zonules, and lung airways(Marcheix, 2008). The heart is also greatly negatively impacted through a weakening of the aortic wall, progressive aortic dilatation or aortic disjointing can occur because of strain caused by left ventricular contractions. Marfans occurs evenly in men and women and can be inherited from just one parent. Marfan syndrome is also referred to as... ... middle of paper
1.0 Introduction Valves are mechanical devices that control the flow and gases in the process. They are essential components of piping system that conveys liquid, vapor and gases. They come in variety of material ranging from steel and plastic. There are different types of the valves such as globe, gate, ball, plug and check valve. Each of these valves has different features and functional capabilities. Some valves can self operated (automatically) while the other manually or with pneumatic or hydraulic

Deciding Layouts Deciding the layout is a very important step in Java GUI programming, just like solving an algorithm in normal programming. Layout decides how the components like labels, buttons, text fields etc are going to be displayed on a frame or window. Some GUI can be designed using single panel with a single simple layout. Some GUI need to be broken down into smaller panels which have to be added to an outer panel. Each smaller panel can have its own layout. The simplest layout is the
A wise man once told me “With any engine project, a solid foundation is necessary” (Jewett). Racing has been a major part of my life ever since I was little. While growing up, my uncles working on cars and racing together has impacted me. When I was little, I watched my uncles race, and it made me want to race when I got older. However, the instructions for rebuilding a twenty-three-hundred motor include the type, bottom end and the head. The fundamentals about rebuilding a twenty-three hundred
which the tricuspid valve is malformed and the valve itself is not in the correct anatomic place (Mayo Clinic Staff). This anomaly affects the right side of the heart – the tricuspid valve is located too deep into the ventricle, causing a smaller and weaker right ventricle. The space above the decreased right ventricle is made up of atrial tissue and this can be referred to as right ventricle dysplasia or an atrialized right ventricle (Reynolds). Typically the tricuspid valve has three freely moving
trying to escape an elaborate dungeon with the help of dimensional doors to navigate through the dungeon’s gauntlets and mazes.
